So if the first one is a letter, there starts with 26 combinations. For each one of those combinations, the second number can take 10 values. Think going 'a1,a2,a3....,b1,b2,b3...' And that is 26x10. If the last entry is also a letter, and can be the same as the first letter, then it is just x26 again, so the answer is 26x10x26 :)
